Hi Sage:
This patch based on my previous patchceph: fix bugs about handling
short-read for sync read mode.
I can't see this patch in ceph-client#testing.Maybe you forget it ?
Thanks!

Hi James,
I'm working on adding jerasure as a plugin to Ceph. If I remember correctly the
next version of jerasure was scheduled to be released this month. Although
using jerasure-1.2 ( as found at
http://web.eecs.utk.edu/~plank/plank/papers/CS-08-627.html ) would be perfectly
fine, it may be
Hi Sean,
I tested out the patch and unfortunately had the same results as
Andreas. About 50% of the time the rpoll() thread in Ceph still hangs
when rshutdown() is called. I saw a similar behaviour when increasing
the poll time on the pre-patched version if that's of any relevance.
Thanks

Tried it. Injected with 'ceph tell osd.* injectargs --
--no_osd_recover_clone_overlap', then stopped one OSD for ~1 minute.
Upon restart, all my Windows VMs have issues until HEALTH_OK.
The recovery was taking an abnormally long time, so I reverted away from
If the raring guest was fine, I suspect that the issue is not on the OSDs.

This might sound a bug harsh but maybe due to my limited english skills ;-)
I still think that Cephs recovery system is broken by design. If an OSD

Sure but remember if you have VM random 4K workload a lot of objects go
out of date pretty soon.

Hi Ceph devs,
I'm working on doing some structuring/designing plugins for RGW. In a
recent discussion with Yehuda, I'm looking into how we can statically
link 'plugins' into the RGW core (so, not really plugins, but more of
a code separation).
However, the ceph automake structure doesn't use

How would you feel about creating two RbdSnapInfo objects. The first
would be something like ceph.rbd.RbdSnapInfo and the second would be
ceph.rbd.jna.RbdSnapInfo. The former is what will be exposed through
the API, and the later is used only internally. That should address
the hacky-ness

Currently the fscache code expect the netfs to call fscache_readpages_or_alloc

Adding support for fscache to the Ceph filesystem. This would bring it to on
par with some of the other network filesystems in Linux (like NFS, AFS, etc...)
In order to mount the filesystem with fscache the 'fsc' mount option must be

It's not really possible at this time to control that limit because
changing the primary is actually fairly expensive and doing it
unnecessarily would probably make the situation much worse (it's
mostly necessary for backfilling, which is expensive anyway). It
